Progressive Depletion of Rough Endoplasmic Reticulum in Epithelial Cells of the Small Intestine in Monosodium Glutamate Mice Model of Obesity

Figure 3

Representative electron microscopy images showing the distribution of rough endoplasmic reticulum (rER) in small intestine mucosal epithelial cells. Mucosal epithelial cells from control mice ((a) low magnification; (b) high magnification). Mucosal epithelial cells from monosodium glutamate- (MSG-) induced obese mice ((c) low magnification; (d) high magnification). Arrowheads in (b) and (d) indicate rER. Scale bars in (a) and (c) = 5 μm and (b) and (d) = 2 μm.
